thanks guys, right now the holes I found are just out of the water, so looks like in a day or so I will have to move them. Not sure where I will move them to. I have two 330's set close by for what I believe is a beavers den. It's an older den that looks to have been freshened up recently. And the what I am calling rat holes are nearby, guess I will keep looking for a rat hole under or close to under the water. They really are "DAM Varmints" as they seem to always dig in the dam area of the pond.
